我正在使用以下代码在R中创建一个boxplot:

boxplot(perc.OM.y ~ Depth, axes = F, ylim = c(-0.6, 0.2), xlim = c(3.5, 5.5),
        lwd = 0.1, col = 8, 
        ylab = "Loss of Percent Organic Matter per Year", cex.lab = 1.5)
axis(1, at = c(3.5, 4, 5, 5.5), labels = c(" ", "Shallow", "Deep", " "), 
     cex.axis = 1.5)
axis(2, cex.axis = 1.5)

问题是y轴上的数字标签当前与轴标题重叠.有没有办法在轴标题和轴号标签之间放置更多空间？

谢谢
